alejandritohi, does manila have quota per volume type ?12:47
alejandritoor share type ?12:47
alejandritoesker, ^^12:48
vponomaryovalejandrito: you mean limit share not by project/user, but by share type?12:51
vponomaryovalejandrito: anyway, share types are out of any quotas12:52
*** huyang has quit IRC12:52
alejandritovponomaryov, so how do i define quotas per storage backend / project ?12:54
vponomaryovalejandrito: set quota by amount of gigabytes and shares12:54
vponomaryovto all - set default, to someone - set by project12:55
vponomaryovor user of project12:55
vponomaryovuser quota can not exceed project quota12:55
nidhimittalhada@vponomaryov : http://paste.openstack.org/show/483418/ could you please reply when you get time.. will see in offline logs.12:57
*** nidhimittalhada has quit IRC12:57
*** houming has quit IRC13:00
*** haomaiwang has quit IRC13:01
alejandritovponomaryov, so that's the way ?13:01
*** haomaiwang has joined #openstack-manila13:01
vponomaryovalejandrito: things that you can use for quotas are following: amount of shares, amount of snapshots, amount of share gigabytes, amount of snapshot gigabytes and amount of share networks13:02
vponomaryovalejandrito: if you have some specific use case, then you can describe it in details and it can be proposed for development13:03
alejandritovponomaryov, so what about quotas per volume type / project ?13:11
alejandritovponomaryov, does that exists ?13:11
vponomaryovnidhimittalhada: yes, in general, describe chain of action in http://paste.openstack.org/show/483418/ is correct13:11
*** haomaiwang has quit IRC13:11
vponomaryovalejandrito: only project / user13:11
vponomaryovalejandrito: share types are out of quota consideration13:11
*** haomaiwang has joined #openstack-manila13:12
alejandritovponomaryov, share types and volume types are the same =?13:12
vponomaryovalejandrito: you can make some share type private13:12
vponomaryovalejandrito: yes, "volume type" is old name that is replaced with proper one "share type"13:13
alejandritovponomaryov, so, making a share type private makes shure that quota is only applied to that project ?13:14
vponomaryovalejandrito: not exactly, private share types are available to projects that you specified for it13:14
vponomaryovalejandrito: so, you can have share type for set of projects13:15
vponomaryovalejandrito: but not quota for share type still13:15
alejandritovponomaryov, perfect thank you, so ... how do i propose quota per share type ? i want to be able to put quota per PLATINUM, GOLD AND BRONZE SHARE TYPER for a specific project, but i do want to offer those share typer to all projects13:17

vponomaryovalejandrito: there is no such possibility, in Manila for the moment13:20
alejandritovponomaryov, so ... how do you fragment storage backends per project ? i mean ... how do you offer a public service using manila ?13:21
alejandritovponomaryov, or a private ?13:21

*** xyang1 has joined #openstack-manila14:47
bswartzso the problem without mounting filesystems in LXD containers14:48
bswartzerr14:48
bswartzthe problem with mounting filesystems in LXD containers14:48
bswartzI'm pretty sure the mounting has to be done in the host container14:48
aovchinnikovyes, sort of14:48
bswartzor at least the host container has to be involved14:48
bswartzso how are doing it in the current LXD driver implementation?14:49
bswartzand is the problem related to mounting or something else?14:50
aovchinnikovdo you mean current version with samba?14:50
bswartzI assume the mounting of the underlying filesystem would be the same with samba or ganesha14:50
*** martyturner has joined #openstack-manila14:50
bswartzis that not correct?14:50
aovchinnikovoh, got it. mounting seems to work just fine14:51
aovchinnikovit is accessing anything that is mounted which is broken14:51
*** cknight has joined #openstack-manila14:51
*** Yogi1 has joined #openstack-manila14:51
aovchinnikovyou can mount a share defined inside a container14:51
bswartzokay14:51
aovchinnikovbut that's all you can do with it14:51
aovchinnikovin case we run nfs-ganesha14:52
aovchinnikovif it is a samba share then everything works smoothly14:52
bswartzso I don't understand why the mounting would affect access14:53
aovchinnikovthe last thing I've found before switching to testing samba was that somehow file access rights get corrupted somewhere14:53
bswartzif the users inside the container can access the filesystem, then everything should work fine14:53
bswartzI wonder if there is some UID translation happening between the guest container and host container14:54
bswartzIdeally there would not be, but if guest containers can have their own password files, then I can see problems start to appear14:54
*** merooney has joined #openstack-manila14:56
aovchinnikovwell, I've tried doing that as root. uids looked identical to me, but nothing has changed14:57
bswartzso do you know at what level the access is getting denied?14:57
bswartzis it happening inside ganesha? or when ganesha attemps to access the filesystem? or is there some layer between the guest and host where access can be denied?14:58
aovchinnikovsomewhere inside  the vfs level14:58
bswartzis the VFS subsystem container-aware?14:58
*** a_ta has joined #openstack-manila15:00
aovchinnikovI can't answer this question, I have not checked it15:00

*** haomaiwang has joined #openstack-manila15:02
aovchinnikovyet this should not be a problem since it is ganesha who does the sharing15:03
bswartzyes it seems to me like the problem has to be in ganesha15:03
bswartzbut if we have a working example of ganesha without containers then it seem very strange15:03
*** xyang1 has quit IRC15:04
aovchinnikovI've tried running it in a separate VM and it worked fine15:04
aovchinnikovso it has to do something with containers15:05
*** xyang1 has joined #openstack-manila15:06
bswartzLinux containers play lots of games with "namespaces" which is a collection of kernel features to support containerization15:06
bswartzI can see various things related to user namesspaces, filesystem namespaces, and mount namespaces15:06
aovchinnikovI thought about summoning gdb to help, but the problem is that it might take too much time15:06
bswartzI suppose any of those things could cause issues15:07
bswartzare there any alternative NFS daemons that we could experiment with?15:07
*** gregsfortytwo has quit IRC15:07
bswartzI know nfs-kernel-server is not an option15:07
bswartzbut perhaps unfsd?15:08
aovchinnikovI've seen several mentioned, but I am not sure that they are mature enough15:08
aovchinnikovwe can give it a try15:08
bswartzyeah I don't think unfsd is mature enough to actually use, but for debugging it's probably way less complex than ganesha so it might help us find the issue15:08
*** gregsfortytwo has joined #openstack-manila15:09
aovchinnikovthat sounds like an option15:10
aovchinnikovprobably we should try it after I am more or less done with samba implementation15:12
bswartzif we can demonstrate a working driver with unfsd and the only problem exists with ganesha, then we can call in the genasha experts to help us solve that issue15:12
*** vbellur has joined #openstack-manila15:15
aovchinnikovok, then I suggest the following: first I finish adding some essential meat to driver implementation that uses samba, then I try unfsd.15:17
aovchinnikovif nothing unexpected happens I think I'll be done with the first part tomorrow15:18
aovchinnikovdoes that sound good?15:18
bswartzyeah that sounds fine15:18
bswartzI'd like to wrap up whatever parts we can15:19
bswartzbut I'm still concerned about the loose ends because we have to address all of them before we can have a new first party driver15:19
aovchinnikovif everything goes as planned we'll have two of them: ganesha issue and neutron15:20
aovchinnikovok, then I'll keep working on the first part of the plan15:23
